Application filed January 1?, 1924.. Serial No. 686,757.

To all whom it may concern:

lie it known that l, EARL (l. Monms, a citizen of the United States, residing at Chicago, in. the county of Cook and State of .l llinois, hzwe invented. certain new and useful Improvements in Pliers, of which the following is a specification.

This invention relates to pliers having a pair of fulcrumed jaws, one of which is so shaped as to adapt the instrument to be used for forming loops or bends in a wire.

In addition to fulfilling the purpose named, it is an object of my invention to produce a pliers which is capable of form-- ing a wire bend or loop to a predetermined size; to further construct the forming jaw so that the operationof bending a wire may be performed with the utmost ease and dcpondability; and generally to provide a pliers answering to the above requirements which will be inexpensive, durable and simple of manipulation.

A11 embodiment of this invention 1s set forth in the accompanying drawing where- .in-- I Figure 1 is a side elevation of the pliers;

Fig. 2 which is a similar view of the working end of'the pliers, shows a slightly modified construction; and

Fig. 3 is an enlarged detail in section, taken on line 33 of Fig. 2.

The pliers of this invention may follow usual constructions to the extent of employing two handles 1%; and B each formed with jaws A and B respectively. As by means of a pin or screw 0 which constitutes a fulcruin for the jaws, the two handles of the pliers are pivotally connected.

' The exact form of thejaw A is of minor importance. As shown, it is provided with a work engaging face 5 which is flat, but obviously this may be otherwise shaped, if desired. The associated jaw B is Special- 1y formed to provide two or more bend or loop forming surfaces. As shown in the accompanying drawing, those are two in number, but obviously may be increased, if desired. These surfaces designated by the numerals v6 and 7, are each by preference circular in cross section (see Fig. 8), providing thereby a form around which a wire 8 may be bent or looped to the extent desired. These forming surfaces 6 and 7, whether they be two or more in number, are each separated by a shoulder 9 resulting from the abrupt change in jaw diameter where such surfaces are adjoined.

It is contemplated that each of these forming surfaces may be substantially cylindrical in ontour, with a uniform diameter from end to end, and, if desired, with a diameter which corresponds to a predetermined gauge size. From this it results that if a wire be wound around any one of these surfaces intermediate of its length, the resulting bend will be uniform asto radius. [is shown in Fig. 1, the two cylindrical surfaces 6 and 7 are coaxially disposed with the result that the shoulder 9 is annular. The purpose of this invention may be fully served, however, by having the axes of these two cylindrical surfaces eccentric as shown in Fig. 2, in which event it is preferred that they be in co-tangential relation along the line which is closest to the engaging face 5 of the jaw A.

A's. illustrative of the manner in which the present pliers may be used, I have shown. in Fig. 1, in crosssection, a wire 8 positioned for bending around the forming surface 6. During this operation it is firmly held in place with the aid of the jaw A, pressure being applied upon the two handles A and B to secure this result. A different curvature to the wire may be obtained if the same be positioned adjacent the cylin-' drical surface 7 as shown by the dotted circle in Fig. 1. Similar methods of illustrating two positions of the wire for bending about the surfaces 6 and 7 are also shown in connection with the instrument of Fig. 2.

From the preceding description, it will be apparent that the present pliers may be advantageously employed wherever a wire is to be handled and bentin the form of a loop or otherwise. The two jaws may be used generally for wire gripping purposes, but, as above explained, are especially adapted to the bending operations described. lVhen the workis once positioned upon the forming surface selected, it may be rested against the end shoulder thereof which acts as a stop to prevent endwise movement of the wire in one direction.

rested, and the other jaw having a face adapted to engage the work when positioned operatively against either of said 10 surfaces, substantially as described.
